“B” pillars (in width)
3.2.2. The halo hoop (labeled “9” in Figure A) may be constructed of either a U-shaped bar
appropriately attached to the main hoop and two front vertical legs (labeled “2” in Figure A),
OR front vertical bars bent rearwards at the roof line, connecting to the rear main hoop and
cross-braced horizontally along the upper windscreen line.
3.2.3. Two continuous/unbroken driver-side door bars are required (labeled “7” in Figure A) that will
prevent cockpit intrusion. NASCAR-style or X-design (with gussets) is acceptable.
3.2.3.1. The spacing between the fore and aft terminal ends of all door bars (including X-design)
must include a separation of no less than six inches of open space when measured at
the center-line of each bar. Triangulated bars that meet or join at the front hoop are
allowed so long as the spacing of the upper and lower bars (attached to the main hoop)
is a minimum of six inches when measured at the centerline of the tubing bar.
2023-V2.0 https://champcar.org 103.2.3.2. The upper door bar shall not be placed higher than the bottom of the driver’s window.
3.2.3.3. If the distance, measured at any point between the highest portion of the door sill or
floor pan (whichever is higher) and the lowest edge of lower door bar is greater than ten
inches (10”), a floor or lower-sill intrusion bar (labeled “8”), mounted as low as possible
on each side of the roll-cage, at or just above the door sill, joining the front vertical legs
and the main hoop is required.
3.2.3.4. A minimum of one (1) door-bar shall be required on the passenger side. This bar can be
a floor, or sill, or mid-level door-bar.
3.2.4. Appropriate main-hoop rear-supports (back-stays, labeled “6” in Figure A) with no bends,
located as close to 45 degrees from horizontal as practical are required.
3.2.5. One main-hoop diagonal support bar (labeled “3” in Figure A) installed in the same plane as
the main hoop, with one end terminating in general proximity to the main hoop bend above
the driver’s head and the other end terminating in general proximity to the lower end of the
opposite side of main hoop is required. The diagonal support bar may be of one (1) or two (2)
piece construction and it may intersect with or cross-through the horizontal support bar (used
for seat belt harness attachment and/or seat support).
3.2.6. Complete 360-degree welds are required at all welded joints. All welds to be sufficient in heat,
penetration, bead, and consistency.
Figure B
3.2.7. Each major load-bearing member must be formed from its own single, continuous tube.
3.2.8. A shoulder-harness bar (labeled “4” in Figure A) mounted just below the driver’s shoulder level
is required.
3.2.9. A dash bar (labeled “5” in Figure A) is mandatory.
3.2.10. Roll-cages are limited to eight (8) body and/or frame mounting points – welded and/or bolted.
3.2.10.1. The total number of mounting points does NOT include a sub-frame to support a seat
mount, provided that the seat sub-frame does not exceed two (2) chassis contact pads.
There is no limit to the number of bars allowed for free between the main hoop to the
front A-Pillar down bars.
3.2.10.2. The total number of mounting points does NOT include welded tabs connecting any
hoop to the body. A “tab” is defined as being not greater than 3/16” thick steel plate, no
2023-V2.0 https://champcar.org 11longer than six inches (6”), and a maximum of two (2) tabs may be placed within any 36”
of tube.
3.2.10.3. The total number of mounting points does NOT include pedal box/foot well bracing
contact pads.
3.2.10.4. Where cages are attached to the vehicle unibody, tubes must be welded to a minimum
1/8” steel plates no less than 16 square inches in size.
3.2.11. Additional Bars:
3.2.11.1. Roll-cages may not have more than four (4) tubes installed behind the main hoop and
two (2) of these must include the main hoop rear-support (back stay) bars without value
add. There is no limit to the number of bars allowed for free between the main hoop to
the front A-Pillar down bars.
3.2.11.2. Roll-cages MAY contain a maximum of four tubes (two per side) for pedal box / foot well
bracing.

driver.
3.2.12.4. Properly bent, quality tubing is mandatory. No stretched or crushed bends allowed.
DOM mild steel is very strongly recommended over ERW tubing.
3.2.12.5. The radius of all bends of the roll cage (measured at centerline of tubing) must not be
less than three times the diameter of the tubing.
3.2.12.6. All attachment points on the vehicle must be selected and reinforced as necessary so
that, in an accident, the roll-cage will not punch through, tear, or grossly distort any roll-
cage attachment point. Heavily rusted floor pans must be replaced or reinforced with

extremity may contact the tube. SFI 45.1 Rated Roll Bar Padding is required wherever a helmet
may contact the roll cage.
3.2.16. In order to prevent massively expensive roll-cages that start to look and act like a tube-frame
chassis, ChampCar has defined the “maximum, value-free” roll-cage. The “maximum, value-
free” roll-cage includes all pads, points, tubes and triangulations necessary to maintain an
extremely high degree of safety, while keeping costs in check and competition well balanced.
Teams MAY exceed the design and application of the “maximum, value-free” roll-cage;
however, additional value will be assessed by the Tech Inspector, based on the perceived
performance enhancement of the roll-cage.
